IMPROVEMENT IN' CARPET-LININGS.

-Specification forming part of Letters Patent No. 222,813, dated Deeember23,i1i879; application filed February 20, 1879.

To all whom 'it may concern:

Beit known that I, AMos F. CHASE, of Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Carpet-Linings, of which the following is a specification.

The object of my invention is to provide a carpet-lining which shall be cheap and simple in manufacture and durable in quality, said lining being composed of such material that the dust, grit, or other l similar substances which sift through the carpet may pass read-y ily through the lining and lie upon the floor. To this end my invention consists in alayer of straw cut of a length equal to the width of one breadth of the carpet-lining, said straw being laid between two layers ot' netted or reticulated fabric, and secured thereto by two or more rows of stitching placed near the edges of l each breadth in such manner that each strand of the straw is fastened to the netted covering at two or more points near the ends of said strands.

Referring to the drawings forming part of this specification, Figure lis a plan View with part ot' the upper netted fabric cut away to show the ber and the lower piece of netted material. Fig. 2 is a section of Fig. l upon the line of stitching.

A, in the drawings, represents the entire lining, whichis composed of alayer of straw, C, of suitable thickness placed between two pieces of netted fabric, B D, the whole being united by stitching, as at c c, of which there may be any desired number of rows placed at any suitable distance apart, although I consider the number shown in the drawings to be amply sufficient to confine the straw in place.

For the fibrous filling C, I use straw, which I lay parallel with the width of the fabric B D, or as nearly parallel as may be convenient, in order that the ends of the straw may be held by the two rows of stitching a a.

I regard straw as preferable to most other materials f'or the filling of my earpet-linin g, as it is light, clean, somewhat elastic, and eX- eeedingly tough and durable, as well as cheap.

For the fabric B D, which is placed above and below the straw filling, I employ any textile material which is very coarsely woven or netted. The fabric shown inthe drawings is a coarse grade of the ordinary mosquito-netting, which answers the purpose admirably. This fabric is cut into strips of about a yard in width, the straw or other fiber is laid be; tween, and the ends trimmed to the same width as the netted fabric, the lining being then fed to the stitching machines, by which it is completed.

Itis obvious that this lining will readily permit dust, dirt, or other comminuted material to pass through and rest upon the floor. The importance of this result may be estimated when it is compared with the result attained by the ordinary ilnpervious carpetlining. In the latter the dirt or dust which is sifted or driven through the carpet lies direcily between the latter and the upper surface of the lining. Thence it is drivenby every step or blow, and in the case of carpets which have been long laid, sweeping or walliing over the surface will cause the dust to rise in clouds.

In my invention, however, this is wholly prevented, the dust passing readily through itihe texture of the lining and lying upon the oor.

Vhen it becomes necessary to remove the accumulation, the lining may be taken up and shaken or beaten like an ordinary carpet without the slightest injury. 1 i

I am aware that it is not new to. use straw for lining, and that straw has been stitched together without covering for such a purpose. I am also aware that a lining has been in vented in which a filling of cotton is employed, covered by a coarsely-netted fabric, and that it has been proposed to substitute moss for the filling instead of cotton. I do not, therefore, claim such as my invention; but

What I do claim, and desire to secure by Letters Patent, is

A carpet-lining composed of an intermediate layer of straw of uniform length, or substantially so, covered upon its upper and lower surfaces by a coarsely-netted or reticulated fabric, the whole being united together by two or more rows of stitching running parallel with the length of fabric, and at right angles to the strands of the fllin g, as set forth. In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.
